We were there Dec 18 and they did check us a few times. They did not scan our tickets when we went in, however. We saw several groups passing the tickets to others waiting on Main St. and I assume those people would just go up front and get their bands. I think it would be much better if they emptied the park prior to letting the party people in. I think its the only way to ensure those who pay for the party get it, and those who have not paid, dont.
The party was fun, but I dont know that it was worth $55 or whatever we paid for it. The park was pretty crowded. The parade and fireworks were shown other nights so they were not unique to the party. The cookies and hot chocolate was nice, but really, is it worth the $$$.. probably not for us. I liked the atmosphere, but there was a holiday atmosphere other nights, too.
